Kupanga Mabodi a Ceramic Circuit Board: Ndizinthu ziti zomwe zimagwiritsidwa ntchito?

Mu positi iyi yabulogu, tiwona zida zazikulu zomwe zimagwiritsidwa ntchito popanga matabwa a ceramic ndikukambirana kufunikira kwawo kuti akwaniritse ntchito yabwino.

Popanga matabwa ozungulira a ceramic, zida zosiyanasiyana zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti zimagwira ntchito komanso zodalirika. Ma board a Ceramic circuit, omwe amadziwikanso kuti ma ceramic printed circuit board (PCBs), amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza zamagetsi, zakuthambo komanso zamagalimoto chifukwa chamafuta awo abwino kwambiri, kutentha kwambiri komanso mphamvu zamagetsi zamagetsi.

Ma matabwa a ceramic amapangidwa makamaka ndi kuphatikiza kwa zida za ceramic ndi zitsulo, zosankhidwa mosamala kuti zikwaniritse zofunikira za ntchito zosiyanasiyana.

1. Ceramic gawo lapansi:

Maziko a bolodi la ceramic ndi gawo lapansi la ceramic, lomwe limapereka maziko azinthu zina zonse. Aluminium oxide (Al2O3) ndi aluminium nitride (AlN) ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi ceramic. Alumina ali ndi mphamvu zamakina kwambiri, matenthedwe apamwamba kwambiri komanso kutchinjiriza kwamagetsi kwabwino, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana. Aluminiyamu nitride, kumbali ina, imapereka mawonekedwe abwino kwambiri amafuta ndi mphamvu zowonjezera kutentha, kupangitsa kuti ikhale yabwino kwa mapulogalamu omwe amafunikira kutentha kwachangu.

2. Njira zotsatsira:

Ma trace a conductive ali ndi udindo wonyamula ma siginecha amagetsi pakati pa zigawo zosiyanasiyana pa bolodi yoyendera. M'mabwalo ozungulira a ceramic, zowongolera zitsulo monga golide, siliva, kapena mkuwa zimagwiritsidwa ntchito popanga izi. Zitsulo izi zidasankhidwa chifukwa champhamvu kwambiri zamagetsi komanso kugwirizanitsa ndi magawo a ceramic. Golide nthawi zambiri amakondedwa chifukwa chokana dzimbiri komanso mphamvu zamagetsi zokhazikika, makamaka pakugwiritsa ntchito ma frequency apamwamba.

3. Dielectric layer:

Zigawo za dielectric ndizofunika kwambiri pakutchingira ma conductive trace ndikupewa kusokoneza kwa ma sign ndi mabwalo amfupi. Zida zodziwika bwino za dielectric zomwe zimagwiritsidwa ntchito pama board a ceramic ndi galasi. Galasi ili ndi zida zabwino kwambiri zotchingira magetsi ndipo imatha kuyikidwa ngati wosanjikiza pang'ono pamagawo a ceramic. Kuonjezera apo, galasi la galasi likhoza kusinthidwa kuti likhale ndi mtengo wokhazikika wa dielectric, zomwe zimalola kulamulira bwino kwa magetsi a bolodi la dera.

4. Chigoba cha solder ndi chithandizo chapamwamba:

Chigoba cha solder chimayikidwa pamwamba pa zowongolera kuti zitetezedwe kuzinthu zachilengedwe monga fumbi, chinyezi, ndi okosijeni. Masks awa amapangidwa kuchokera ku epoxy kapena polyurethane-based materials zomwe zimapereka chitetezo ndi chitetezo. Gwiritsani ntchito mankhwala ochizira pamwamba monga malata omiza kapena plating ya golide kuti bolodi lisasunthike komanso kuti mupewe makutidwe ndi okosijeni a mkuwa.

5. Kudzera kudzaza zinthu:

Vias ndi mabowo ang'onoang'ono omwe amabowoleredwa kudzera pa bolodi yozungulira yomwe imalola kulumikizana kwamagetsi pakati pa zigawo zosiyanasiyana za bolodi. M'mabwalo ozungulira a ceramic, kudzera pazitsulo zodzaza zimagwiritsidwa ntchito kudzaza mabowowa ndikuwonetsetsa kudalirika kwamagetsi. Zodziwika bwino pogwiritsa ntchito zida zodzazitsa zimaphatikizapo phala la conductive kapena zolembera zopangidwa ndi siliva, mkuwa kapena tinthu tating'ono ting'onoting'ono, tosakanizidwa ndi magalasi kapena ma ceramic fillers. Kuphatikiza uku kumapereka kukhazikika kwamagetsi ndi makina, kuonetsetsa kugwirizana kwakukulu pakati pa zigawo zosiyana.

Powombetsa mkota

Kupanga matabwa a ceramic kumaphatikizapo kuphatikiza zinthu za ceramic, zitsulo ndi zinthu zina zapadera. Aluminium oxide ndi aluminium nitride amagwiritsidwa ntchito ngati magawo, pomwe zitsulo monga golidi, siliva ndi mkuwa zimagwiritsidwa ntchito potsata njira. Galasiyo imakhala ngati zida za dielectric, zomwe zimapatsa magetsi, ndipo chigoba cha epoxy kapena polyurethane solder chimateteza ma conductive. Kulumikizana pakati pa zigawo zosiyanasiyana kumakhazikitsidwa ndi zinthu zodzaza zomwe zimakhala ndi ma conductive phala ndi ma fillers.

Kumvetsetsa zida zomwe zimagwiritsidwa ntchito popanga matabwa a ceramic ndikofunikira kuti mainjiniya ndi opanga apange zida zamagetsi zodalirika komanso zodalirika. Kusankha zinthu zoyenera kumadalira zofunikira zenizeni zogwiritsira ntchito monga matenthedwe matenthedwe, mphamvu zamagetsi ndi chilengedwe. Pogwiritsa ntchito mawonekedwe apadera a chinthu chilichonse, ma board a ceramic akupitiliza kusinthira mafakitale osiyanasiyana ndikuchita bwino komanso kulimba kwawo.
